[0021] Please see Figure 1-6This utility model provides a multifunctional integrated nursing record pen, comprising: a pen body 1, a pen cap 2, a pen tail 3, a miniature LED bead 4, a replaceable pen refill 5, a pupil comparison ruler 6, a drainage fluid colorimetric card 7, a power supply unit 8, a miniature nerve reflex hammer 9, and a control mechanism 10. The pen body 1 is the core load-bearing structure of the entire device, integrating all functional modules. Its lower end is threadedly connected to the pen tip 1001, facilitating subsequent disassembly and replacement of the pen refill 5 while maintaining structural stability and ease of maintenance. The pen cap 2 is fitted onto the lower end of the pen body 1, protecting the pen tip 1001 and the pen tip of the replaceable pen refill 5 from damage or ink leakage during idle periods. Furthermore, a protective cover 21 fixed to its lower end provides storage space for the miniature nerve reflex hammer 9, preventing contamination or deformation during non-use and ensuring hygiene and tool integrity during clinical operations. The pen tail 3 is threadedly connected to the upper end of the pen body 1, facilitating disassembly and maintenance of the internal circuitry. The electronic display screen 11 and its control circuit on the pen tail 3 are the core of the time and timing functions, enabling electronic watch, timer, and stopwatch functions. The miniature waterproof button 12 on the side is used to operate these functions; its waterproof design can withstand splashes of disinfectant and patient bodily fluids in the clinical environment, extending the device's lifespan. The miniature LED bead 4 provides a light source for pupil examination, solving the problem of unclear pupil observation due to insufficient light in the clinical environment, eliminating the need to carry an additional flashlight. The replaceable pen refill 5 enables basic writing functions for recording patient care information; its replaceable design reduces usage costs. The pupil comparison ruler 6 is used to quickly compare the patient's pupil diameter, assisting in determining whether the pupil size is normal, eliminating the need to carry a separate paper pupil ruler and reducing tool switching steps. The drainage fluid color chart 7 determines whether the drainage fluid is abnormal by comparing its color with the patient's drainage fluid, providing a visual reference for condition assessment. The power supply unit 8 provides power to the miniature LED bead 4 and the electronic display screen 11, ensuring stable operation of all electronic functions and serving as the energy core for the device's "electronic" functions. The miniature nerve reflex hammer 9 is used to examine a patient's tendon reflexes, assisting in the assessment of nervous system function, replacing the traditional independent rubber hammer, and reducing the number of tools to carry. The control mechanism 10 is the switch for the miniature nerve reflex hammer 9, precisely controlling the hammer's pop-out and reset, ensuring ease of operation and preventing the hammer from accidentally retracting or popping out during use.

[0022] To further clarify, the electronic display screen 11 and its control circuit are common knowledge in the field, and their specific structure and circuit will not be described in detail here.

[0023] Further explanation: The control mechanism 10 includes a sliding seat 101, a connecting rod 102, a cavity 103, a protrusion 104, a return spring 105, a positioning hole 106, and a pressing rod 107. The sliding seat 101 can slide up and down inside the pen cap 2 and is the core component for power transmission. One end of the connecting rod 102 is fixed to the lower side wall of the sliding seat 101, and the other end is fixedly connected to the miniature nerve reflex hammer head 9. The sliding of the sliding seat 101 directly drives the hammer head 9 to move up and down through the connecting rod 102, realizing pop-out and reset. The cavity 103 is opened on the outside of the sliding seat 101, providing space for the protrusion 104 to move. The protrusion 104 slides in the cavity 103, with one end extending out of the outside of the sliding seat 101 to cooperate with the positioning hole 106 for positioning. The two ends of the return spring 105 are respectively connected to the protrusion 104 and the inner wall of the cavity 103. Under normal conditions, it pushes the protrusion 104 outward to ensure stable positioning. When the positioning needs to be released, pressing the protrusion 104 compresses the spring 105, causing the protrusion 104 to retract into the cavity 103. The two positioning holes 106 on the side wall of the pen cap 2 correspond to the "storage position" and "use position" of the hammer head 9, respectively. When the protrusion 104 is engaged in the upper positioning hole 106, the sliding seat 101 is in the high position, and the hammer head 9 retracts into the protective cover 21. When the protrusion 104 is engaged in the lower positioning hole 106, the sliding seat 101 is in the low position, and the hammer head 9 extends out of the protective cover 21. The pressing rod 107 is slidably inserted into the positioning hole 106. When it is necessary to switch states, pressing the pressing rod 107 can push the protrusion 104 back into the cavity 103, releasing the positioning restriction and facilitating the movement of the sliding seat 101.

[0024] To further explain, a protective sleeve 22 is fixedly connected inside the pen cap 2 to protect the tip of the replaceable pen refill 5. This sleeve fits over the outside of the tip of the replaceable pen refill 5. Compared to the overall protection of the pen cap 2, the protective sleeve 22 fits the tip more precisely, preventing wear caused by friction between the tip and the inner wall of the pen cap 2, and also preventing ink leakage from the tip from contaminating the inside of the pen cap 2. A spring 23 is located between the lower side wall of the protective sleeve 22 and the sliding seat 101. Normally, this spring is compressed, storing elastic potential energy. When the control mechanism 10 is released, the spring 23 releases its potential energy, pushing the sliding seat 101 downwards. This, in turn, causes the miniature neural reflex hammer 9 to automatically pop out via the connecting rod 102, eliminating the need for manual pulling of the hammer, reducing operational difficulty, and improving ease of use.

[0025] To further explain, the miniature LED bead 4 is located on the side of the pen tip 1001. The miniature LED bead 4 is a surface-mount LED. Compared with traditional through-hole LEDs, surface-mount LEDs are smaller in size and consume less power, which can save internal space of the pen body 1. At the same time, they have higher luminous efficiency, ensuring that they can still provide sufficient brightness under low power consumption and extend the battery life of the power supply unit 8.

[0026] To further explain, the pupil comparison ruler 6 is set on one side wall of the pen body 1 by precision printing, and the drainage fluid colorimetric card 7 is set on the other side wall of the pen body 1 by precision printing. The areas of the pen body 1 where the pupil comparison ruler 6 and the drainage fluid colorimetric card 7 are located are all coated with a wear-resistant and alcohol-resistant coating.

[0027] To further explain, the wear-resistant and alcohol-resistant coating is a water-based polyurethane coating, which can resist frictional wear during daily use and prevent the scale of the pupil comparison ruler 6 and the color markings of the drainage fluid colorimetric card 7 from becoming blurred due to wear, ensuring the accuracy of assessment data during long-term use. At the same time, it can withstand routine clinical alcohol disinfection operations, preventing alcohol corrosion from causing scale fading and colorimetric card distortion, ensuring the long-term usability of both assessment tools.

[0028] To further explain, the power supply unit 8 is a lithium battery built into the pen body 1. The pen body 1 is equipped with a charging interface 13 that is compatible with the power supply unit 8. The power supply unit is electrically connected to the micro LED beads 4 and the electronic display screen 11 respectively.

[0029] To further explain, the charging port 13 adopts a universal standard such as Type-C or Micro-USB, which makes it convenient for nurses to use common hospital chargers without the need for additional dedicated charging equipment.

[0030] To further explain, two symmetrically distributed guide grooves are provided on the inner side wall of the pen cap 2, and a slider that matches the guide grooves is fixedly connected to the outer side wall of the slider 101. This can limit the movement direction of the slider 101, prevent the slider 101 from rotating or deviating during movement, and ensure that the connecting rod 102 drives the miniature nerve reflex hammer 9 to pop out or reset in a straight line, preventing the hammer from being unable to be properly stored or used due to deviation.

[0031] To further explain, a switch button for controlling the miniature LED beads 4 is provided on the outer wall of the pen body 1.

[0032] It should be noted that this utility model is a multifunctional integrated nursing record pen. In use, the pen cap 2, which is fitted onto the lower end of the pen body 1, is removed, exposing the pen tip 1001. Holding the pen body 1, the replaceable pen refill 5 is used to record patient information on the nursing record sheet. During recording, if time needs to be recorded simultaneously, the real-time time displayed on the electronic display screen 11 at the end of the pen can be viewed directly, without needing to consult a watch. The miniature LED bead 4 is activated by the switch button on the pen body 1, illuminating the patient's pupil. The nurse places the pupil comparison ruler 6 on one side of the pen body 1 close to the patient's pupil and reads the pupil diameter using the scale on the ruler 6 to determine if the pupil size is normal. After the assessment, the miniature LED bead 4 is turned off to avoid wasting electricity by keeping it lit for an extended period. The nurse removes the patient's drainage bag, observes the color of the drainage fluid, and, holding the pen body 1, compares the color of the drainage fluid with the color of the drainage fluid using the color chart 7 on the other side of the pen body. The nurse determines if the drainage fluid is normal based on the standard color on the color chart 7. After comparison, the drainage fluid color result can be directly recorded on the nursing sheet using the replaceable pen refill 5. When checking nerve reflexes, the patient sits with their lower legs hanging naturally. The nurse holds the pen body 1 in one hand and presses the pressing lever 107 on the side wall of the pen cap 2 with the other. The pressing lever 107 pushes the protrusion 104 on the sliding seat 101 back into the cavity 103, releasing the protrusion 104 from the upper positioning hole 106. At this time, the pop-out spring 23 inside the pen cap 2 releases potential energy, pushing the sliding seat 101 downwards along the guide groove, and driving the miniature nerve reflex hammer 9 out of the protective cover 21 via the connecting rod 102. When the protrusion 104 slides to the lower positioning hole 106, the reset spring 105 pushes the protrusion 104 into the lower positioning hole 106, the sliding seat 101 stops moving, and the hammer 9 remains in the pop-out state. The nurse gently taps the quadriceps tendon below the patient's patella with the popped-out miniature nerve reflex hammer 9, observing whether the patient's lower leg exhibits involuntary extension movements, thus completing the examination. After the examination, the nurse presses the lever 107 on the side wall of the pen cap 2 again, causing the protrusion 104 to retract into the cavity 103, releasing the positioning of the lower positioning hole 106. The nurse manually pushes the miniature nerve reflex hammer 9 upwards, causing the sliding seat 101 to slide upwards until the protrusion 104 engages with the upper positioning hole 106, at which point the hammer 9 retracts into the protective cover 21, completing the reset. When pulse measurement is required, the nurse touches the patient's radial artery with their finger while simultaneously pressing the miniature waterproof button 12 on the side of the pen tail 3 to activate the timer function on the electronic display screen 11. The nurse counts the number of pulse beats, and after one minute, presses the button again to pause the timer, reading the duration on the display screen 11 and recording the pulse count. When measuring respiratory rate, the nurse observes the rise and fall of the patient's chest or abdomen, presses the miniature waterproof button 12 to activate the stopwatch function, counts the number of breaths within one minute, and records the result after the stopwatch finishes. After use, wipe the surface of the pen body 1 with an alcohol swab to disinfect and sterilize, and avoid cross-infection.
